01 -  Preheat the oven to 350°F. Lightly grease a standard 6-cup muffin tin or line with silicone muffin cups. 
 02 -  Boil the ramen noodles according to package instructions, omitting the seasoning packet. Drain well and briefly rinse under cold water. 
 03 -  In a bowl, combine soy sauce, sesame oil, mirin if using, sugar, and green onion. Toss the cooked noodles with this mixture until coated evenly. 
 04 -  Divide the seasoned noodles evenly into the muffin cups, pressing gently to form nests. 
 05 -  In a separate mixing bowl, whisk eggs, milk, salt, and white pepper together until completely blended. 
 06 -  Evenly pour the egg mixture over the noodles in each muffin cup. 
 07 -  Top each muffin with sesame seeds, nori flakes, and shredded cheese as preferred. 
 08 -  Transfer muffin tin to the oven and bake for 18 to 20 minutes, or until eggs are firm and lightly golden. 
 09 -  Let muffins rest for 5 minutes before removing from the tin. Serve warm or at room temperature.
